Since I'm using Xcode 9, all unit tests communicating with keychain are broken. It also happens with Xcode GM. As I traced, there is no OSStatus errors while reading and writing but reading from keychain returns nothing and causes failure for all unit tests using keychain. I've already faced something like this when Apple released Xcode 8 with iOS 10 simulator which keychain was not working and Apple fixed that in Xcode 8.2. Is anybody else facing this issue with iOS 11 simulator too? Any idea on this? Elyas Naranjee Sani Finally we found the problem. As @Gix said the problem is with unit

i use a piece of code for drop shadow on a view with help of slider. Slider is set -15 to 15. This code works awesome when slider.value is positive but app stop working if its negative. the crash log is weird Terminating in response to backboardd's termination . i got this log first time. What is that? here is my code. childViews.layer.shadowColor = [[UIColor blackColor] CGColor]; childViews.layer.shadowOffset = CGSizeMake(slide,slide); childViews.layer.shadowOpacity = 1.0; childViews.layer.shadowRadius=10; childViews.layer.masksToBounds = NO; childViews.layer.shouldRasterize = YES; backboardd

I want to run functional (UI) tests for the login procedure in my iOS app (Xcode 7.2.1). The app's behaviour is that upon successful login, user credentials are stored in order to automatically login (without showing the login screen) in the next launches. So I set up a sequence of UI events in the login screen to make the login test pass on the first time the app launches in the iOS Simulator. However, next times I run my tests will fail, since the login screen doesn't even show up as expected. I see two options here, none of them seem to fit well: Reset iOS Simulator's content and settings

My problem was how to set the gps location of my app when running in the iOS simulator The home screen in my app displays sunrise and sunset times based on gps location and I wanted a screen shot with sensible values - I'm in the UK and the sunrise times were showing UK times for American sunrise and sunset. As it is on the launch screen one solution, going to Debug -> Simulate Location, is too late for me. Took me a while to work out and I wasn't finding the answer when I searched here (maybe not asking the question the right way . So I'm going to answer my own question below in the hope it

Since iOS 8 was released the default device type for simulator became iPhone 6. And even if I manually change the device type using Hardware > Device menu, on the next launch (using rake simulator ) the simulator will revert to iPhone 6. I wonder if there is any rake options, or some other settings to force the device type. PS. I know that there are ways to force a non-retina iPhone and a way to launch the iPad simulator instead of the iPhone one, but I'm interested in selecting between 5/6/6+.
